Timing is everything: Expert opinion on researching epilepsy rhythms by the ILAE Task Force on Chronobiology. [PDF]
EpilepsiaAbstract Recurrent seizures, the hallmark of epilepsy, are influenced by rhythms operating over multiple timescales. Chronobiology is the study of biological timing that aims to explain temporal patterns of events like seizures. Fueled by recent advances in genetics, computational modeling, and device engineering, the chronobiology of epilepsy is now a

Time after time - circadian clocks through the lens of oscillator theory. [PDF]
FEBS LettOscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Could photoperiodic responses have evolved before the emergence of circadian clocks? [PDF]
New PhytolSummary Plants use photoperiod (i.e. day length) as a seasonal cue for timing when to flower. This ability, known as photoperiodism, also underlies phenomena such as migration, seasonal reproduction, and hibernation in animals. Because a circadian (daily) clock underlies the day/night length timing mechanism in most organisms, it has been generally ...

Digital Sleep Disruption: Unraveling the Network Structure of Technology Use and Sleep Problems Through Network Analysis. [PDF]
CNS Neurosci TherIn 9443 Chinese adults, network analysis reveals blue light exposure as the central factor most strongly associated with sleep problems (r = 0.31). General screen time shows minimal direct effects (r = 0.03), with sleep disruption mediated through evening‐specific behaviors.

Twenty-Four Hour Rhythms in Cardiovascular Physiology. [PDF]
Acta Physiol (Oxf)ABSTRACT Many physiological parameters, such as heart rate and blood pressure, display pronounced daily rhythms, with significant differences between day and night levels. The ability to anticipate the 24 h cycle of ambient light confers an adaptive advantage, allowing organisms to prepare for periods of activity and rest.

Atlas-Based Mapping of Traditional Chinese Medicine Effects on Tumor Microcirculation Regulation. [PDF]
Immun Inflamm DisABSTRACT Background Tumor microcirculation plays a central role in the onset and progression of hypoxia, therapeutic resistance, and immune evasion within the tumor microenvironment. Traditional Chinese Medicine (TCM), characterized by its multi‐targeted and systemic regulatory properties, has garnered increasing attention for its potential to modulate

BMC Nursing, 2021 Background Young adults are likely to have activities and go to bed late at night due to their age-dependent delayed endogenous circadian clock. The purpose of the present study was to clarify sleep–wake rhythm and its association with lifestyle, health ...

A Multi-Layered Study on Harmonic Oscillations in Mammalian Genomics and Proteomics [PDF]
, 2019 Cellular, organ, and whole animal physiology show temporal variation predominantly featuring 24-h (circadian) periodicity. Time-course mRNA gene expression profiling in mouse liver showed two subsets of genes oscillating at the second (12-h) and third (8-
